In regards to typesetting, one minor issue I noticed was at times the text was hard to read bc it was small/thin compared to the rest of the comic. This can be an issue specifically for those with disabilities such as dyslexia. I think either making the font bold or switching to one specifically made for comics would work best. For other fonts (I'll only recommend free ones) I know Anime Ace is a popular one, but I personally use CC Astro City since it's a little less stylized. If you're looking for a font that isn't all caps, Arial Rounded MT Bold is another great option. Last, a more niche pick would be UD Digi Kyokasho which is actually a Japanese font, but the Enligh letters are really reader-friendly. I hope this helps.
